Sister cities

Twinned with San Antonio

7 of 12 in this atlas

San Antonio maintains twinning agreements with municipalities across several continents, including Chennai, Guadalajara, Gwangju, Kaohsiung, Monterrey, Windhoek, and Wuxi. Each of these pairings is mutual, meaning both cities name each other formally. The connections span Asia, Africa, and North America, reflecting a spread rather than concentration in any single region, at least according to this atlas's records.
